This takes place primarily in the CTU where that invader left the nerve gas. Unfortunately, they didn't seem to have anything in place to combat this. There were numerous casualties. I once again hope I never see Kim Bauer again. She and her lack of basic gratitude doesn't need to be part of this. There is a lot of heroism in this episode. Meanwhile, the Vice President is showing his ambition, knowing that the President is really a wimp. There are shakeups coming at CTU very soon. And then there is Collette.
